SCALE CASE.

Application filed February 28, 1924. Serial No. 695,690.

This invention relates to scale cases and has particular reference to cases for double dial suspended or column supported types, and the object of the invention is to cheapen the cost of making and assembling the case, and also to provide a distinctive and more ornamental appearance than has previously been obtained.

As will be understood, the scale case to which this invention relates is the sheet metal casing enclosing the scale frame and carrying on opposite sides the scale sashes surrounding the dials, these sashes sometimes having glass to cover the dial and sometimes not. used for many years in this type of scale case joins the two sashes by inserting one within the other and then inserting small holding screws. These screws are difficult to insert because very accurate work is required in making the holes register and in tapping them so as to hold the screws, and the holes frequently get out of alignment owing to distortion or inaccuracy of the sashes. Moreover, this form of joint produces a narrow seam or ridge around the middle of the outside of the case which is objectionable in appearance.

By this invention each sash is provided with a flange extending peripherally of the frame in a plane parallel to the dial planes, and a channel member having its sides spaced the distance between these flanges is placed over them and secured in order to hold them together. In some forms of scales this channel casing piece may be in one piece in the form of a split ring whose ends Will be secured to the frame or to each other and which may be slotted at desired places to pass the runner, etc. In the form shown herein this channel member is in the form of two pieces together constituting a substantial ring and the ends are secured by screws. As there may be a certain amount of resiliency in the sashes and mats where used, it is an easy matter to employ this resiliency in conjunction with the locking effect of the channel member to firmly hold all parts such as the sash and mat rings, and lass where used, in firm relation. A most important advantage of the invention is that this channel member as herein shown is of A construction commonly substantial width and gives a distinctive and novel finish and appearance to the scale not heretofore obtained in this art.

In the accompanying drawings,

Fig. 1 is a perspective view of a scale embodying the invention,

Fig. 2 is a section on the line 22 of Fig. 1,

Fig. 8 is a detail showing the runner and the fastening of the case channel sections, and

Fig. 4- shows a modification wherein the glass and mat of Fig. 2 are dispensed with in favor of a single sash ring member for each dial.

1 represents the scale frame consisting generally of an annular box containing the pointer shaft 2 and a pointer 8 on each dial 4. lVithin the case is the usual spring, pendulum or other weighing mechanism not necessary to be further described, but having the runner or other weigh -responsive element 6 extending therefrom. As herein specifically shown the face members of the frame are extended and flanged over as at 7, Fig. 2, to form a support for the sash ring members 8. In Fig. 2, 9 is the glass and 10 the mat ring members. In Fig. 4: the glass is dispensed with and combined sash ring and mat ring 11 performs the same function. The sash rings 8 and 11 are provided with peripheral flanges 12 which are preferably located as far apart as possible while still bearing on the cylindrical flanges 7 of the frame. 13 is a channel memher having flanges 14 to embrace the sash frame flanges 12 as shown in Fig.2, it being seen that the flanges 12, 14 are in planes parallel to the dial sashes. To fasten the ends of the channel member 13, angle pieces 16 are attached by fastening 17to the frame flanges and carry fastening screws 18. If the case member 13 is in two pieces as herein shown there will be four screws for each piece, the separations coming at the runner 6 and hanging lug 19 respectively.

In assembling, the frame will be provided with dials, the sash rings and accessories placed thereon in final. position and then slightly pressed to ether against the natural resiliency while the flanges 14. are placed over the flanges 12 and the screws 18 insert ed, thus firmly holding the parts together without rattling or looseness. It is to be understood that the sash and mat rings may be otherwise fastened without depending upon the resiliency to hold the flanges 12 in engagement with the flanges 14, but in general it is desirable to have at least a tight Sliding lit between these flanges 12, 14:.

This invention does away with the un sightly bead or ridge now common to scales of this type and instead provides the broad, slightly curving surface 13 which can be polished or painted, and which gives a very distinctive, attractive and unique effect while being structurally stronger than the telescoping screwed together constructions previously used, and cheaper to assemble.

Modifications may be made in the details shown without departing from the scope of the appended claims.

I claim:

1. In ascale, flanged front and back sash rinp; members, an annular separable channel member receiving and retaining the flanges of said front and back members therein, and securing means for the channel member.

2. In a double dial scale, a scale frame carrying dials and pointers, a sash ring member engaging and holding the frame around each dial and having a radially arranged flange, an annular channel member having its flanges engaging said sash flanges inside said channel, and securing means for the channel member.

3. In a scale, a resilient sash ring member having a peripheral flange on its outer edge and an interior bearing portion, an outer channel member having a cooperating flan ge overlying said sash flange for retaining it in position, and means for securing the ends of the channel member to prevent separation of said sash member.

l. The combination with a frame carrying opposite dials, of a mat ring bearing on each, a glass on each mat ring, a resilient sash ring bearing interiorly on each and having an exterior radially extending flange, a separable flanged channel member engaging said sash flanges, and means for securing the ends of the latter ring.

5. The combination with a frame having double dials, a suspending means at the top and a runner at the bottom, of peripherally fianged sash members surrounding each dial, means for retaining said sash members and comprising a split channel 1ncm ber receiving the flangesof the sash members, and means securing the channel member to said frame.

Signed at New York city, in the county of New York and State of New York this 19th day of February, A. D. 1924.
